A year ago, after reading through this thread and after playing mk1995's 4-Rooms Levelset, I started wondering if two-room levels could be fun to play.
I think they can be, and I plan to create a mod with nothing but two-room levels that I'll release during the night of 31 December 2013/1 January 2014.
Please join me in creating the best two-room mods we can.

Broken room links are fine, as long as no more than two rooms are being used per level.
I already have some interesting ideas...
